Not able to access my Linux using ssh when disconnected

Post by CesarDBA »

Hello,

I am using VBox in Windows7 and installed Oracle Linux 5 as guest. I am using Bridge Adapter on network settings. When the computer is connected to the router using the ethernet cable adapter everything works fine. But I am not able to connect to the guest using ssh if my ethernet card is down. Is it the expected behavior? If it is, is there any workaround I can use to connect to my guest using ssh when the PC is disconnected, for example, when I am traveling?

Thank you in advance,
Cesar

Add a second adapter set to host-only. See http://www.virtualbox.org/manual/ch06.html

Hi,

Thank you for your reply, but it does not work as I am expecting. Imagine you have the Linux guest set as 192.168.2.122. If you set a new card, using host adapter, you are able to access your new IP provided by VBox, as for example 192.168.1.101. I am able to do a ssh to the new IP (192.168.1.101). But I want to access the Linux IP, 192.168.2.122, as this will be accessed by a browser: http://192.168.2.122. What I want is to use IP 192.168.2.122, instead to use the IP provided by VBox host adapter. I am able to access the IP when I am connected to my router, but not able to access it when my ethernet card is down. Any other workaround for this?

Regards,
Cesar

You have to decide which you want to do. If you use a LAN connected access it of course will not be present when not on the LAN. The host-only is the only way to have both but the address will be different. I believe you can assign both to the web server though.
